The pitfall of a differentation strategy include

not spending enough on advertising and promotional campaigns.

charging too low a price premium for the differentiating features.

not pursuing the same approach to differentiation as other rivals employing a differentiation strategy.

differentiating on the basis of attributes that produce an unenthusiastic response on the part of buyers $($because they do not perceive the differentiating features as valuable or worth paying for$).$

trying to focus simultaneously on most all of the available value drivers to set the company's product offering apart from those of rivals.
